GRAIN-METER.

SPECIFICATION forming part of Letters Patent No. 466,312,- dated December 29, 1891. Application filed May 23, 1891. Serial No. 893.871. (No model.)

Be it known that I, HUGH B. SrINsoN, a citizen of the United States, residing at Morris, in the county of Stevens and State of Minnesota, have invented a new and useful Grain-Weigher, of which the following is a specification.

This invention relates to grain weighing and bagging machines; and the objects in view are to provide a combined grain weighing and bagging machine adapted to be applied to the discharge of a thrashing-machine and to automatically bag and weigh in predetermined quantities grain as discharged from the thrasher.

Other objects and advantages of the invenand the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of a grain-bagging machine constructed in accordance with my invention. Fig. 2 is a reversel side elevation. Fig. 3 is a vertical longitudinal section. Fig. 4 is a detail in perspective of thebag-holding rockarm. Fig. 5 is a detail in .perspective of one of the tripping-arms. Fig. 6 is a transverse vertical section. Fig. 7 is a detail in perspective of the Weighing lever or beam. Fig. 8 is a side elevation of the trip-case. Fig. 9 is a similar view of the registering device with the case removed.

Like numerals of reference indicate like parts in" all the :figures of the drawings.

The casingconsistsof two opposite side walls 1 and 2, the upper front corners of which are curved and connected by a curved wall 3,. The lower end of the casing has its side walls at their lower edges provided with central curved recesses, and the walls of these recesses are connected by a curved bottom wall 4, so that in connection with the side walls, the front wall, and the rear wall 5 a pair of dischargespouts 6 and 7 are formed. To theA opposite sidewalls, immediately above the curved bottom, there is secured, by screws located at suitable points, opposite metal plates 8, and in bearings 9 formed in the opposite plates a rock-shaft 10 is mounted. The rockfshaft 10 has mounted at the side of the 4wall 2 a head 11,from the opposite sides of which project perforated ears 12. Within the casing there is mounted upon the rock-shaft a vibrating cut-off 18, to the upper end of which is hinged, as at 14, a section or leaf 15, provided at opposite sides with outwardly-bent straps 16, adapted to operate as stops andpermit i of the leaf swinging over upon the cut-off only to a certain angle. The interior of the casing is provided with a pair of inclined walls 17 and 18, and when the leaf and cutoff are swung against the wall 17 the grain, it will beapparent, will be directed to the discharge 7, and whenswung to the inclined wall 18 the grain will be directed to the discharge 6.

Below the rock-shaft 10, in bearings 19, there is mounted for oscillation a rock-shaft 20, and upon this rock-shaft, at the ends of the same and outside of the casing, are mounted crossheads or arms 21 and 22, located adjacent to the side walls 1 and 2, respectively. From the cross-head 22, at opposite sides of the shaft 20, depend compoundly-curved arms 24, which latter terminate opposite the discharges 6 and 7 and are provided with curved bagholding plates 23, the outer edges of which are toothed, so as to engage the bag. Arms 25 are secured to the cross-head 21 and extend upwardly from the same to points opposite the discharges 6 and 7 and are provided at their extremities with upwardly and downwardly curved or bent spring bag-holding arms 28, which at their lower ends have secured thereto curved toothed plates 29. It will be evident that bags may be connected to the plates 23 and drawn under the discharges G and 7, and by springing the spring-arms 28 toward the casing the serratedplates 29 may beinserted into the bags, and by the resiliency of the springs retain said bags in position, each under a discharge-spout.

Upon each of the arms 21 and 22 and near the extremities of the same are located per' forated pins 30, and through the same are passed sack-supporting standards 31, terminating in or supporting at their lower ends bag-supporting platforms 32, one located under each of the discharges 6 and 7.

Projecting from the plate 8 of the side wall 2 is a pair of vertically-opposite keepers 33. The extremities of the cross-arm 22 are perforated and are pivoted by bolts 34 to the lower bifurcated ends of a pair of inwardly- IOO curved quadrant-shaped bars 35, said bars meeting at the center of the casing and overlapping each other, and there connected with the lower ends of integrally-formed vertically reciprocating latch -bars 36 and 37, mounted for independentreciprocation in the keepers 33 and provided between said keepers with transverse recesses 3S, in each of which there are pivoted, as at 39, weighted latches 40 and al, the former being located in the recess of the trip-bar 36 and the latter in the recess of the trip-bar 37. These latches have their unweighted ends beveled or inclined, as shown. The perforated ears l2 of the head 1l are pivotally connected by bolts 42 to the lower ends of a pair of links 43, the upper ends of which are pivoted, as at 4i, to the upper curved portions of the trip-bars 3G and 37.

In a keeper 45, projecting from the plate 8 opposite the gravity-latches 40 and 4], is pivoted or fulcrumed at 4G a scale-beam 47. The rear end of the scale-beam is provided with an L-shaped recess 48, and below the same is rounded, as at 49. At the opposite side of the keeper there is mounted upon the beam an adjustable weight 50.

An L-shaped plate 5l is secured tothe wall 2, directly below the scale-beam, and is provided with a slot. beam, and between the terminals of the same there is pivoted, as at 53, a depending rod 54:, the lower end of which is threaded and carries athumb-nut 55, between which and the slotted plate a coiled spring 5G is interposed,

'the tendency of which is to resist the elevation of the scale beam. A bolt 57 passes through one end of the plate, at one side of the slot, and terminates at its upper end in a circular head or disk 5S. Upon this bolt, immediately above, the plate is mounted a setnut 59. The outer end of the scale-beam is bent, as at G0, and is drawn by the spring 56, so as to rest upon the disk o'r head of the setbolt. By a proper adjustment of the set-nut of the bolt the latter may be elevated or depressed so as to bring the opposite recessed end thereof in different adjustments with relation to the gravity-latches.

Secured to the wall 2 is the base-plate Gl of a register mechanism which l may employ in connection with this apparatus. There extends from this plate a stud 62, upon which are mounted three disks, designated as the f inner units-disk 63,the central tens-disk 64, and the outer hundreds-disk 65. The two outer disks each have ten ratchet-teeth, while the inner disk, which is considerably larger, is provided with twenty. The teeth of each disk are numbered in regular order. Abow-spring (56 presses a pivoted lug or paw] 67 outwardly from the rear face of the two inner disks. A bracket 68 extends from the plate of the register, and a pair of flat springs 69 extend downwardly from the bracket, said springs at their free ends engaging with the teeth of the two outer ratchet-disks. The

y A clip 52 embraces the flat springs prevent said disks from retrograding, anda similar flat spring 70, secured to the lower side of the base, performs a similar function for the large inner ratchet G3. A pawl-lever 7l is mount-ed for oscillation upon the stud 62 and at the outer end of the same carries a spring-pawl 72, which engages with the teeth of thelarge ratchet. Over the mechansm thus described is fitted a registered box or case 73, having a sight-opening 74, through which the numerals of the disks as they pass the opening may be Viewed. The ease is also provided with a perforation 75, through which protrudes the end of the stud 62. A bowed spring 76 has its lower end pivoted to the box or casing immediately below the stud, and is compressed until its upper terminal removably engages with a notch 77 formed in the under side of the stud. By means of the spring the box is lockedin a removable manner over the mechanism, said spring by its own resiliency locking itself in position. The outer end of the lever 7l is connected loosely by a connecting-rod 78 to the outer or free end of the scale-beam, so that each movement of said scale-bealn as caused by mechanism heretofore described, and in a manner to be hereinafterdescribed, causes a vibration of the pawl-lever 7l, and at each vibration of said pawl-lever the pawl 72 thereof causes the inner or units disk to be operated one tooth. As the spring-pressed lug of the units-disk passes Linder the flat spring that engages with the tens-disk the same is pressed by said spring into engagement with said tens-disk and the latter operated until it passes beyond the influence of the 'flat spring and is thrown out of engage- 'ment with the ratchet Gi by its own spring. The distance of the engagement is that of one tooth. The lug of the tens-disk operates in a similar manner in connection with the disk 65 and its spring'. In this manner it will be apparent that the movements of the scalebeam which indicate a predetermined amount of grain passing into the bags will be correctly and positively registered by the register, which may at any time be inspected by the operator. 79 designates aboX or case for the upper ends of the gravity-latches, and the same is provided with a perforation near its lower end for the passage of a stud S0, projecting from the lower keeper of the plate S. This stud is provided upon its upper side with a notch Sl, and above the perforation in the box there is pivoted a curved lever S2, the curved or cam edge of which is designed to be swung into the recess of the stud, and thus lock the box in position.

The operation is as follows: The bags, two in number, are mounted in position upon the bagsupports, as heretofore described, their mouths being held distended under the discharges G and 7 of the apparatus. The cutolf being swung to one side or the other directs the grain from the discharge of the thrasher through one of the discharges 6 or 7- IOO IIO

for instance, the discharge G-and continues to flow ltherethrough until a sufficient quantity has passed into the bag tocounterbalance the weight of the scale-beam, which weight, it will of course be understood, h as been previously adjusted. IVhen this has taken place, the crosssbar 22 is depressed at that end thereof at which the arm 24 is located, and also the cross-bar at the opposite end of the shaft'20.. Such movement upon the part of the shaft causes a downward movement upon the part of the curved arm 35 and its trip-bar 36, said trip-.bar by means of its gravity-latch tilting the scale-beam. As the scale-beam is tilted the same, through the medium of the connecting-bar 7S, oscillates the pawl-bar 7l of the register, /andthus said register is operated in a manner heretofore described. As the trip-bar 3G ascends, it, through the medium of the connections 43, oscillates or rocks the shaft lO and swings the cut-off to the opposite side of the casing, thus directing the grain to the opposite discharge 7, where a duplicate operation takes place. The spring 56 of the scale-beam serves to return the pawl-bar 7l and thus operate the ratchets of the register. By the lowering of one arm 24 the opposite arm is elevated and the trip-bar of said arm brought to such a point that. its gravity-latch will engage with the end of the scale-beam, so that when said trip-bar is drawn down the scalebeam will be operated.
